Installation Procedures:
1. Remove the End Plate from the modulator assembly and set each channel with the switches as shown
in Figure 1. Choose unused channels that match the tuning mode of the televisions. With antenna
tuning, choose UHF channels from 14-69.With cable tuning, choose CABLE channels from 70-94 or 100-
125. There must be at least one blank channel on either side of each modulated channel to separate it
from any other broadcast, cable, or modulated source. When combining with cable service, be aware
that digital data typically interferes with channels 80-117, even when not subscribed to digital services.
If no channels are available then a filter such as NetMedia's CNF7080 (ch. 70-80) may be necessary.
2. Connect a coax cable from the camera's F connector to the coax from a television or distribution system.
Connect the 12V DC 300mA power supply to an AC outlet.The modulator picture is now available on the
programmed TV channel.
